i took a MYPAL emergency contraceptive pill within 15 hrs of unprotected sex even though no ejaculation occured. I got my periods about 4 days early but they were light and only for 3 days. My normal cycle is for 5 days and im usually regular. 2 weeks after this bleeding i.e. one month after the intercourse i took a home urine pregnancy test. It came out negative. Also my ultrasound reports came normal. The only thing worrying me is that my previous periods were lighter and for a shorter duration. Is that normal? Also is bloating a side effect of these pills?
